A skill-by-treatment interaction (STI) isolates skill deficits and manipulates conditions to match them to student needs. Based on the learning hierarchy, preintervention scores can help predict which intervention will be most successful for an individual student. This study compared the efficacy of a modeling and practice-based decoding…

Instructional interactions that occur between teachers and students around foundational mathematics topics are critical for supporting mathematical proficiency among students with mathematics learning disabilities (MLD). This study investigated whether the initial mathematics skill of 880 kindergarten students at risk of MLD predicted the quantity…

Universal screening is a critical component of school-based prevention systems. Screening data enable educators to target students for supplemental intervention, align resources to meet needs, and identify students who may be at risk for learning disabilities. One major requirement of the screening process is that all students are included to gain…

Many states now mandate early screening for dyslexia, but vary in how they address these mandates. There is confusion about the nature of screening versus diagnostic assessments, risk versus diagnosis, concurrent versus predictive validity, and inattention to indices of classification accuracy as the basis for determining risk. To help define what…

Students most at risk for reading-related disabilities frequently struggle with word recognition and oral language, including, in the earliest grades, specific skills related to phonological awareness and vocabulary. Classroom teachers' delivery of high-quality differentiated supplemental instruction may promote reading acquisition for these…

This article examined the extent to which administrative decisions that affected the implementation fidelity of Direct Instruction programs were related to student achievement. Data from three studies showed that administrative decisions that disregarded recommended protocols regarding teacher training, teacher preparation, and student schedules…

Oregon's Effective Behavioral and Instructional Support Systems (EBISS) initiative was implemented in 25 school districts. The initiative trained and coached district leaders and teachers in the use of the EBISS model through the lens of implementation science. The EBISS model integrates school-wide positive behavior intervention and supports…

Accumulating research has established explicit mathematics instruction as an evidence-based teaching practice. This study utilized observation data from a multi-year efficacy trial to examine the longitudinal effects of a core kindergarten mathematics program on the use of explicit mathematics instruction among two distinct groups of teachers: one…

The current study examined a solution to high false positive reading risk classification rates in early kindergarten by investigating a method of identifying students with possible false positive risk classifications and returning them to general classroom instruction. Researchers assessed kindergarten students (N = 105) identified as at risk who…

This study examined the changing role and longitudinal predictive validity of curriculum-embedded progress-monitoring measures (CEMs ) for kindergarten students receiving Tier 2 intervention and identified as at risk of developing reading difficulties. Multiple measures were examined to determine whether they could predict comprehensive latent…

For many students at risk of reading difficulties, effective, early reading instruction can improve reading outcomes and set them on a positive reading trajectory. Thus, response-to-intervention models include a focus on a student's Tier I reading instruction as one element for preventing reading difficulties and identifying students with a…

This study examined the effectiveness of a classroom teacher intervention, the Targeted Reading Intervention (TRI), in helping struggling readers in kindergarten and first grade. This intervention used biweekly literacy coaching in the general education classroom to help classroom teachers use diagnostic strategies with struggling readers in…

This study examined the role of home literacy, parental education, and demographic factors in addition to conventional literacy skills at the beginning and end of kindergarten in predicting end-of-kindergarten spelling achievement. The study involved 9 schools and 29 classrooms serving an economically and ethnically diverse population (N = 288).…

This study examined the effects of a supplemental early reading intervention on the beginning literacy skills of 12 kindergarten/first-grade urban English language learners (ELLs). The Early Reading Intervention (ERI; Simmons & Kame'enui, 2003) was the instructional intervention used with all students. A multiple-baseline design across…

Under the accountability provisions of the No Child Left Behind legislation, screening for reading risk has become routine in kindergarten. The objective of this study was to examine the effects of the timing of kindergarten assessment and the type of support provided to teachers to translate assessment results to instruction. Sixty-two schools…
